Bug Description

After upgrading to 1.79.7, I began noticing visual artifacts on my screen. Light blue or light green streaks, sometimes in patterns, sometimes somewhat random. I also began getting environment lockups (especially during flash video play) with messages in the syslog like:

Oct 19 20:03:27 hosanna kernel: [130892.932466] NVRM: Xid (0000:01:00): 8, Channel 00000001
Oct 19 20:03:43 hosanna kernel: [130908.918695] NVRM: Xid (0000:01:00): 8, Channel 00000001

By environment lockups, I mean the video would stop, and I couldn't click on any windows, or use the keyboard, but I could still move the mouse around.

This behavior did not start until after I did a sleep and wake up after the upgrade.

I forced a downgrade, slept the laptop, woke up, and so far I can play flash video without lockups, and have yet to see any visual artifacts.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
